Plant Growth and Development is one of the most important chapters in NEET Biology, covering the processes that regulate plant growth from seed germination to maturity. This chapter explains the concepts of growth, differentiation, development, and the factors that influence these processes. Students learn about growth rates, growth curves, meristematic tissues, and the various stages of plant development.

The chapter also focuses on plant growth regulators (PGRs) such as Auxins, Gibberellins, Cytokinins, Ethylene, and Abscisic Acid (ABA), which control growth, flowering, fruit development, dormancy, and stress responses. Additionally, important topics like photoperiodism, vernalisation, seed dormancy, and plant responses to environmental factors are frequently asked in NEET examinations. A clear understanding of these concepts helps students strengthen their knowledge of plant physiology and improve their performance in competitive exams.
